  • Page 6: Commissioning

    Commissioning Transport Guard In the state as delivered, every pillar of the protective hood is locked in its clo- sed position by transport guard elements, which prevent the supporting spars (20, Fig.16) from being moved. Every time a hood is transported these guards must be fitted to secure the moving parts.

  • Page 7: Handling The Pillars Of The Hoods

    Commissioning Handling the pillars of the protective hood Fig. 3 Ring screw M8, DIN 580 10 (Fig. 16) 300 (Fig. 16) To transport the pillar a ring screw as per Fig.3 should be screwed into the tapped hole provided (10, Fig. 16). The weight of the pillar is shown on the nameplate (300, Fig.16).

  • Page 8: Mounting The Hood

    Commissioning Mounting the Hood Since the hood stands on only two pillars, it must be secured by appropriate means to prevent it toppling. Optimal stability is obtained with a structure in which the pillars of the hood are integral parts of the machine support. Fig.4 to 6 show examples of sup- ports made of Quick-Set fixing elements.

  • Page 12: Equalizing Weights

    Commissioning Equalizing Weights With the equalizing weights (43532, Fig. 16) a balance is obtained between the mass of the hood and that of the counterweights. Once a state of equilibrium has been reached, the hood can be set to any desired position only by the application of an external force.

  • Page 13: Altering The Equalizing Weights

    Commissioning • Move the hood only so far that the upper edge of the weights is roughly in the middle of the opening. • Remove equalizing discs singly by hand or insert them with the slit forwards (as in Fig.16). After an insertion or removal check whether the hood does stand still in any desired position.

  • Page 14: Mounting The Safety Switch

    Commissioning Mounting the safety switch A safety switch must be mounted on one of the two pillars of each hood (as per Fig.23). The safety limit switch (10, Fig.23) is fixed to a plate (20, Fig.23) with screws (50, Fig.23). The plate with the safety switch can be fixed with the clamping element (40, Fig.23) either to the external dovetail of the pillar (50, Fig.16) as shown in Fig.10, or to the external dovetail of a strut perpendicular to the pillar (50, Fig.16) in a suitable position as shown in Fig.11.
  • Page 15 Commissioning Fig. 11 The safety switch must be positioned so that the actuating arm engages in the slit in the switch housing when the hood is closed, thereby actuating the switch. The safety switch must be electrically connected so that the hazardous device is switched off at once when the hood is opened and cannot be switched on again before the hood is closed.

  • Page 16: Drop Guard

    Commissioning Drop Guard The drop guard prevents the hood from dropping down if the belt (40, Fig.16) or its mounting (110, 140, Fig.16) breaks. If the tensile force of the counterweight transferred by the belt to the bracket (20, Fig.24) becomes ineffective for any of the reasons given, he energy stored in the two springs (50, Fig.24) forces the bracket downwards.This movement actuates the two pawls (30 and 40, Fig.24), which immediately engage in the dovetail of the pillar (50, Fig.16).

  • Page 17: Retrofitting Of Drop Guards

    Commissioning Retrofitting of Drop Guards Retrofitting of drop guards may only be carried out by qualified persons. On both pillars the holder (70, Fig.16) has to be replaced by a drop guard. Procedure: • Lower the hood as far as the stop. •...
  • Page 18 Commissioning • Push the assembly aid (45459, Fig.12) with the pins first into the holes (10 mm dia.) of the drop guard support until resistance is encountered. • Press the assembly aid further against the spring pressure, until the plate of the aid is against the support of the drop guard.

  • Page 20 Commissioning • By slackening and turning out the screws (150, Fig.16), remove the holder (70, Fig.16) and bushes (80, Fig.16) from the supporting spar (20, Fig.16). • By slackening and turning out the countersunk screws (140, Fig.16), remove the holder (110, Fig.16) from the belt. •...
  • Page 21 Commissioning After mounting the drop guards • Remove the holding devices (45515 Fig.13) from the belt. For this purpose, the synchronous shaft must be pressed about 10 mm away from the bearing block (10, Fig. 16) as when mounting the holding devices, and the shaft (30, Fig.

  • Page 22: Maintenance

    Maintenance Replacing the Belts Material: Chlorbutadiene elastomer CR (Polychloroprene) with steel strands The belts are highly resistant to the weather and ozone, also to acids and alka- lis as well as to most oils, but are not resistant to aromatics. For closer details see ISO 1817.

    Maintenance Adjusting the play of the guide rollers To eliminate undesired play from the guides, proceed as follows: • Having loosened and turned out the panhead screw (260, Fig.19), remove the cover (220, Fig.19) by pushing upwards out of the groove in the suppor- ting spar (10, Fig.19).
